Please I don't really knw why AT&T blackberry torch phones don't have 3G only as a mobile network option just 2G and 2G&3G as options. Pls help, how do I unlock this option cos am tired of using 2G&3G cos of most of the time it stays on EDGE. Is there anyway out?

If you were to be able to switch to 3G only (which is not possible) you would have mostly no service in an area where there is mostly just Edge. That's the reason devices do not have the 3G only option.Posted via BlackBerryForums.com Mobile

ATT is currently set (in most areas) to hand DOWN from 3G to 2G if you are making a call. This leaves more resources for DATA on UMTS. Text MSG's try and go 2G if possible also. These are all carrier settings that they adjust in response to traffic demand. Keep in mind that 3G UMTS is 100% a noise driven network You can have signal from multiple sites but if the signal to noise is too high you will not setup a connection.

In my case it does serve a useful purpose to be able to lock it on 3g only. Edge service is barely usable at my house, but 3g works great (1 bar if you're lucky on edge, usually upwards of 3 bars, sometimes full service on 3g). I use the e screen to do it.Posted via BlackBerryForums.com Mobile
